There are several reasons you may find yourself needing a new HVAC system, whether due to age or damage. Some of the most common reasons are mentioned here:
The Age of Your System
Regular maintenance from HVAC technicians can keep your unit running well for years. However, eventually every HVAC will need to be replaced simply because of their age. Some units can last up to 15 years, but most homeowners consider replacement after 10 years. Even if units are still running after a decade, their components will begin to deteriorate. In addition, over a 10 year period, many updates can be made to how HVAC systems function, and switching to a new unit may save you extra utility costs that can come with running an old unit.
One way homeowners can gage if their unit is starting to struggle is the smell it emits. Some smells, such as the smell of burning dust, can be a normal part of your HVAC function. You’re especially likely to smell this when you turn on your heater for the first time after the summer months.
However, other smells can mean serious problems. For example, if you smell gas, often described as similar to the smell of rotten eggs, this could mean a gas leak in your unit. In this case your unit should be turned off immediately and you should call a professional to examine it.
Poor Air Quality
If your older HVAC system is emitting strange smells, this can also affect your air quality. During the winter, even in Central Texas, many homeowners keep windows shut tight against the cold. If your HVAC isn’t operating at peak condition, you could be shutting yourself inside with poor quality air. Things to look out for include excessive dust in your home and abnormal humidity. Both of these issues can indicate that your HVAC is not functioning properly, either due to age or damage.
Can’t Keep Home Comfortable
The main purpose of your HVAC system is to keep your home at a comfortable temperature during the winter and summer. When your unit starts struggling to maintain the desired temperature, it’s often a sign that it can no longer supply the required air to your home. This can be due to age or damage, either of which can lead to a need for replacement, especially if your unit is old. Having an HVAC professional access your unit can help you decide if damage is the case and the unit can be repaired, or if the unit has simply reached the end of its life.
Energy Bills Increase
When you start noticing your HVAC system being unable to maintain your desired home temperature, you may also notice your utility bills going up. If your unit is no longer powerful enough to condition and circulate air in your home normally, it will have to work harder to keep up. When the unit starts working harder than it should have to, it uses more resources. You’ll notice this change across your energy bills as they will begin to increase. If your unit cannot keep your home comfortable and starts costing you more money while trying, it’s usually best to replace it.
